SS or Tube Preamps with Dual-Balanced outputs

Here's some correction for Esoteric and JRDG:

** Esoteric C03 PreAmp (new)(1 xlr output)
** Jeff Rowland Capri 1 Bal-XLR, 1 Unb-RCA std)
** Jeff Rowland Concerto (std)
** Jeff Rowland Criterion (std) 2 Bal XLR

Guidocorona,
Thanks for corrections, are you certain about the rowland gear, I read on their website transformer coupled, I don't know enough about circuitry so I may be wrong, but I thought that when preamp is not fully balanced it uses transformer in there to create a balanced output.
Please educate me.

Rowland components have been differentially balanced since at least early nineties. So much so that the TI Burr Brown OPA1632 module used in Capri and Criterion is a differentially balanced OP Amp. G.

Thanks Guidocorona.

Pedrillo/Guido: Great to hear from you. Thanks for updating the list to answer a key capability I am looking for that I already enjoy in my CP-700. I had reviewed the Esoteric early materials on the C-03 and believe the ** designation is accurate. That would also make alot of sense given their delivery of fully balanced, dual-mono capabilities from start to finish with the P-03/P-03U/D-03 units. Have a great weekend!

The updated list is now;
